Would be good to know then you got reply. Forum notification (private message or smth) or email message would fit. Now you just need to delve through forum threads till you find (or not) in which you posted.
Also search is a bit uncomfortable? Would be good if had options like "show from newest to oldest" or "search for thread name"/"search for thread author"/"search for thread post".
And finally private messages. Why this forum doesn't have this option yet? ;/
Using the search seems like more trouble than going back through the pages. Can we please at least have it search just a subfolder, like suggestions or arsenal?
