So a list of topics that you initiated, rather than topics in which you are participating, is that it?
Does that sound like a doable option? Not saying do away with what is there, but have a section that lists all the recent topics you initiated. Not just your recent posts.So it would be in addition to and not rather. Doing away with recent posts on that page would not be good.
I use the recent posts all the time, and expand it to show all. So I can track the topics that I have participated in. That is one of the first places I go when I log in. Recent posts section allows you to view if there are any new posts that have been made in relationship to the topics where you joined in.
If there were an advanced search like found in the Find More Solutions it would be great. Find Mors Solutions alows you to search by author, but only solutions. As the Forums get more and more data I believe an advanced search would become more important. I have brought this up elsewhere. Advanced Search that would allow you to search boards by Subject and or Author of subject.
