ok first of read this post hes done on his website :
or if your not willing to read the text
heres the main point summed up
"If you are a member of garrysmod.org, from the 14th of April onwards (to coincide with the Facepunch forum registration) you will now need to pay for the downloads (this is too help with increasing bandwith costs). The cost for a download ranges between 10 pence to around £1, depending on what the newly assigned moderators of Garrysmod.org feel the mod is worth (This will be checked regularly, and the moderators are a unbiased team). Every download which is currently on the website will be checked over the next week for compatibility and copyright, and those which donít match which are required will be removed. This is to help you get the most out of the mod, as well as reduce the number of problems which mods have when garrysmod is updated."
ok so either this is an april fools joke
or if this is serious (which i actually suspect and im not very gullable by the way)
then im afraid that Mr newman has gone too far , ok so i was sorta alright with the registering and making sure gmod is installed (not that i even play it anymore but still) but now he CHARGES for mods
im sorry but hes gone too far imo
