There's Biology Stack Exchange. However, your question is not related to a bioinformatics problem, so it will have to be closed.

You might get a less chilly response, and your post might stay open if you were to ask it in the forum, rather than in this main question section. It also helps to make some direct comment linking your interest in a biology forum to bioinformatics (believe me, nothing is too obvious).

It really depends what you are looking for, biology is a big place... in any case a few options extracted from my bookmarks of such things:

• Biology - Stack Exchange
• BioStar
• SEQanwers
• Protocol Online
• OpenWetWare
• BIOSCI/Bionet
• Bioinformatics.org Groups

You can also search Google Groups for relevant groups, for example: https://groups.google.com/forum/#!forumsearch/biology, or look for forums via a Google search: http://www.google.com/search?q=biology+forum
