TO answer your question though yes the bronze would be enough to host a nuke site. Most of my nuke sites even with photo galleries installed rarely get close to 50MB of disk space. And most of the nuke sites I host (I have 3) have between 20 and 75 users and my bandwidth has never been above 1GB a month. Now I am sure a site that hosts a lot of downloads like nukemods probably uses a lot more bandwidth, but if your site is just going to be for a small userbase that bronze package should be plenty. Also better to start low and then upgrade to a bigger package if need be. Most hosts let you upgrade for no charge, you just start paying the higher rate for the package you choose.
I'll go ahead and throw in a promo for my host though while I am here. The host you are looking at uses the Ensim control panel whereas mine uses Cpanel which I find much easier and more useful to use. Really comes down to a matter of personal preference. But my hosts plan looks to have everything that that bronze package had and it is slightly less expensive at only $30 bucks a year. Check out
Jatol.com The coolest thing with them is they have a 7 day trial period as well something I haven't seen any other hosts offer. So you can sign up and test drive the functions and features for 7 days to see how thier service is. You can even upload your whole site during that time if you wish. Then if you like it you pay them through 2checkout.com and start ftp'ing up your stuff. If you don't like thier service then you just walk away no questions asked. Pretty slick. Also the admins there are very helpful and responsive. They answer questions via a help desk, Instant messenger, or thier forums. Regardless any issue I have had I have never had to wiat longer then 10 minutes to get an answer. Most hosts you email them and you are lucky if you get an answer in 24 hours. They are the best host I have found to date, and I have hosted with a few.
