Forum comments, forum search, and attachments
Forum comments should stand out more, as they are easily missed. Perhaps a very subtle blinking or something. Or by default, comments should be expanded or a different color text or something.
Being able to search a forum is imperative. Obviously the ability to type a lot of stuff and not being able to search the verbiage isn't very efficient.
I think that forum attachments should be listed instead in the Documents area in a category named "Forum Uploads." (Only reference/links to these attachments should appear in the forum.) This consolidates all downloads into one area instead of accidentally losing an upload because it's somewhere in the depths of the forum. All files should be in the Documents area.
Finally, when sending a copy of a forum post or comment to a user, you are provided w/ a copy as well. This should be OPTIONAL because all comments sent regarding your post look identical to the post you sent when viewing zoho emails in your inbox. (The subjects and senders of your post email and the comment emails are identical.) By not sending yourself a copy, you won't accidentally ignore a comment email regarding your post.
I believe TinyMCE or some basic WYSIWYG functions should be included. After all, we all want bullets, bolding, italics, etc. to effectively emphasize things.
