bbPress 2.5.4, WordPress 4.0, Theme: Accelerate.

Font size does not depend on the theme.
Extra small font is not convenient read.
Please do, the size of 16px.

I can do it myself, I know the file bbpress.css.
But also for the new font size need to customize the size of all the blocks of the forum.
The names of the words in different languages ​​have different widths blocks.

[Vadim]

The words “Voices” and “Replies” can be replaced with icons.
(bbp-forum-topic-count, bbp-forum-reply-count)
This saves space.

I did so:
Font was larger, but the design has changed.

/* Я */
#bbpress-forums ul.bbp-lead-topic,
#bbpress-forums ul.bbp-topics,
#bbpress-forums ul.bbp-forums,
#bbpress-forums ul.bbp-search-results {
	font-size: 15px;
}
#bbpress-forums .bbp-forum-info .bbp-forum-content,
#bbpress-forums p.bbp-topic-meta,
#bbpress-forums .bbp-forums-list li,
div.bbp-template-notice p,
#bbpress-forums div.bbp-the-content-wrapper textarea.bbp-the-content {
font-size: 15px !important;
}
#subscription-toggle { 
background: #E7FFE8;
margin-left: 5px;
padding: 0px 3px 0px 1px;
border-radius: 2px;
font-size: 15px;
}
/* /Я */
