Found the solution for the “nofollow” in signatures, similar to the one you proposed for posts:
https://bbpress.org/plugins/topic/bbpress-signatures/page/2/#post-3179
Ooops, I think we posted at the same time. Ok, I tested it and it works so now all links in the message area are nofollow with no holes and the profile has the follow as I wanted. Very good 
Thank you, mwaterous.
mwaterous, thank you again. Did I say thank you?
I followed your advise and created the file functions.php where I placed that line of code and incorporated it to the bbpress theme at the root. This worked equally well. The only url that wouldn’t get the “nofollow” is the one at the signature. Never thought about the upgrade issue
Correct, the signature corresponds to _ck_’s plugin. Never thought about that either. Perhaps I should contact him privately for adding a piece of code? (maybe I should read discussions on this topic too.)
Style sheet solved. Yes, it was an issue with the “textarea” field. Problem was actually “cache” on my browser that wouldn’t let me see the changes. So I flush the dns and all was working fine.

I have found another bug in another plugin “subscribe to topics” where after activation admin will only be able to logout from within the forum. Attempting to logout from the admin panel will result in a serious of errors:
Warning: Cannot modify header information – headers already sent by (output started at /home/skincare/public_html/bbpress/bb-includes/functions.bb-core.php:596) in /home/skincare/public_html/bbpress/bb-includes/backpress/class.wp-auth.php on line 292
Should I discuss the above 2 topics (signature and subscribe-to-topics) in the corresponding threads?
Hi, mwaterous. That is FANTASTIC. Thank you!
I have to run some more tests but I think you nailed it. I tested:
Test.com
http://www.test.com (simply written www, no html)
http://test.com (http: but no html)
<a/ a tag)
Except for the 1st one, all were converted into a link and ALL carried the nofollow tag. This is for posting messages by members on regular threads.
I placed that last line anywhere inside /bb-includes/functions.bb-formatting.php, as I didn’t have any of the other files you mentioned. In case others need this, is it possible to stick this one up? When I researched this subject here I found a few topics with at least 7 or 8 members looking for an answer to this problem. But the only answer was provided by you today.
Still ONE MORE spammer alert: if a member places HTML in its signature (using the <a tag) this will escape your filter and the signature will go “follow”
On another subject, if I may…
1. Signatures: do they only appear in the first post made by the member? I believe so.
2. I messed up the .css and can’t refix it. The size of the font for the “textarea” where messages are entered is close to nothing and I have to glue my eyes to screen to read what I am writing. This is the only field where the font-size was nuked. Where and in which .css should I fix this?
Thanks!
Thank you, mwaterous! This works perfectly.
Now, the profile link is “follow”, the url link in messages continues to be “nofollow” and the HTML link (<a) continues to be “follow”. So this will be the only issue… it is just too tempting.
As for spam, yes, I am walking on the razors edge. But the forum is by invitation/contribution only. Not for anyone that wants to register. As members contribute, I figure a real link is the least I can offer… as in gratitude.
How do I file a trac for #1 problem?
