I think you need some new discussion topics too. Have you considered getting someone for a fee maybe from a place like Fiverr to open maybe a few accounts and post some topics through them? Like it's probably not 100% integrity. But if you do it in a very small dose just so that you can get a Forum that new quality members can post to easily, maybe that would encourage those kind of members to join up. The place you can look for someone to do is is at this link: https://www.fiverr.com/categories/writin...hp_cat_sec
How about doing some advertising at LowendTalk.com, webhostingtalk and freewebspace.net? Should be easy - just a nicely laid out thread with all of the specs and info and then copied to the three places. I haven't seen anything recently at freevps.us either.
