I use DreamHost
. Let me know if you decide to go with them though. I'll get a referral credit, and I believe I can get you a discount as well.
Otherwise, for free, in the spirit of Inkscape, I would gladly host this forum. That might include me hosting the domain, and then me giving you the ownership. That may not be appropriate for you, so if you are looking to purchase hosting, I'd still suggest DreamHost
In fact, I went ahead and put my affiliate link in those DreamHost URLs. I can also make specific discounts for you (which comes out of my $97 referral award). Which, in the spirit of Inkscape I'd gladly do. Private message me if you are interested.
By the way, their customer service and turnaround times are by far the best I have ever encountered.
