I guess my board has grown beyond the 100MB limit my ISP has allowed me. Seems hard to believe since my message board is somewhat small...but I guess it is. So now I need to do some maintenance to pare it down a bit...can anyone give some good advice on what to do?

I have never pruned topics...is that what I need to do? When I do that do they disappear forever?

Will clearing the cache help?

And I recently did some exporting of member files and posts...can I delete the the txt files in the Import/Export directory?

As always thanks in advance for your thoughts and suggestions!
