Is it appropriate to reply to old forum posts?

[PCBiology]

hello,

I registered for this site based on a couple of reasons, 1 - while I was in college I found a lot of help here without needing to post anything new, and 2 - I was recently reading a topic and felt compelled to reply but then realized the topic was 10 years old so now maybe I shouldn't reply? What do you think?

Either way I hope to impart some of the little knowledge I do have to help others - I'm a biology teacher so I'll be living over in that sub forum mostly.

Alrighty then

It's usually frowned upon if you "reanimate" long dead threads. It's better if you start a new one instead.
