Heya and welcome to the forums
. Actually it is even weirder to think that during almost the entire time MTVMG series were still in production that there were practically no online community about them. Most people just posted their songs on their personal site. I think the problem was that a lot of people posted songs with premade riffs only and little to no originality, which made others have a bad opinion about the softwares, then people told them to use better studio programs which caused other people like us to be afraid of posting our music online. THis is not to mention around the time the best two MTVMG came out fewer people had internet and a lot of people still had dialup, which isn't convenient for sharing music. Around the MTVMG3 days there was finally a MTVMG-related site called Console Musicians and it was about every console music making programs including Ejay Clubworld and Magix Music Maker PS2. I'm unsure if it covered Mario Paint though. Unfortunately it was apparently very inactive and it eventually shutted down. I think part of the problem was that people bashed these music softwares back in the days because they didn't even bothered figuring out there was a riff editor and said it was too limited. Also I don't think the site allowed you to upload your songs directly, but I could be wrong. If you couldn't upload your songs then it was most likely problematic because at that time there were barely any file hosting websites like savefiles and barely any decent free web hosting.
TIMGUL came out 3 years too late but i felt it was a good idea because people were starting to upload their music more and more on Youtube but it was hard to find. I didn't thought that many people still used these programs though. Actually that site could be probably seen as a retro gaming site too by some people if it stays open longer, because Music and Music 2000/MTVMG are from the '90s and some people are starting to talk about PS1 games as retro gaming, as they started to do about 5 years ago with SNES games.
Given that we are still hard to find I think we will continue getting more members though, unless everyone active left. The only real way to become easier to find by other people would be that as many members possible include a link to this site in their signatures on other forums they visit (altough I think the link would have to include the words MTV Music Generator, something like "TIMGUL: a forum about MTV Music Generator (Music 2000) series", which would not necessarly draws more members directly, but would boost google rankings, as google ranks sites based on how much places it is linked from
