Hopefully if an SEO plugin comes out it won't be nearly as resource intensive as the old vBSEO.
That plugin made every forum I visit noticeably slower. Unless its gotten better in the past year or so.
I noticed you said that this forum will be "competitively priced".
While I'm willing to switch from vB to support the developers I grew to love from Jelsoft. I am not however willing to pay $161+ for a forum software.
I felt you should know how I felt, because I'm sure your looking to gauge...
