Re: Limiting my forum’s post size
Just a note: that field length can be bypassed in the browser, if someone wants to. If you don’t modify the database field, it probably won’t be a problem and it will prevent people from just posting things that are too long. I think a better way would be to verify that the input is less than 3000 characters with a plugin, before trying to insert it into the database.
Maybe a combination of the two. Give people a counter showing how many characters are left (like eBay does in some of their forms) and then have a plugin verify what is being submitted actually conforms to your rules.
