This thread's main post has been updated as iSoaker.com is being made modification/homemade-building free. However, iSoaker.net is in the process of expanding its modification and homemade information availability. This may not be the optimal choice for some, but it does try to make the most of emerging opportunities while not losing out on the development of new content in the modification and homemade building world. Granted, iSoaker.com has always been primarily focused on stock water blasters so the change in rules does not require significant changes to the site.
Edit: rest assured, I will not remove general modification and homemade creation from iSoaker.net (notwithstanding purely dangerous mods/builds). If it ever becomes necessary, iSoaker.net can always be renamed if it needs to be further differentiated from iSoaker.com, but hopefully it never comes to that. iSoaker.net, being a membership driven site, is built to support as much of the overall water warfare community as it can. The only content that will be restricted/removed are those inherently dangerous, profane, illegal, and/or for mature-audiences-only.
