If you do a search for "webhost" you should get a tonne of threads with a tonne of info. From those results I'd then search again each page for "webhost" or "host" as there is a lot of noise in threads. After a quick look myself, here are some threads to get you started:
So, uh. Webhosts. Again. (started for non-OOTP reasons, but some OOTPers gave some good info)
http://www.ootpdevelopments.com/boar...ll-2007-a.html (don't get excited about free being in the title, he was just looking for one)
http://www.ootpdevelopments.com/boar...directory.html (idea never really took off, but Fidel listed his there... feel free to add more)
Note that some posts may be years old and CommishJoe's service was sold to another company so who knows what it is like now. There are still numerous recommendations both positive and negative though. You'll also learn a lot more by reading those threads (like features you might want/need) than just finding recommendations for webhosts.
One of the most popular services with OOTPers with
Fidel's AllSimBaseball.com service. I personally have never used his service, but many here do and he does go out of his way to help people here so I'm sure he's even more so with his company.
It'd be great if some commishes could also chime in with the amount of space, bandwidth, etc one would want to look for in a hosting plan. Beware that OOTP 2k7/8 leagues require a lot more than OOTP6.5- leagues.
