Feel the mana power growing inside you!

There used to be a pretty awesome site called lgdb.org that was a database for games available on linux. I searched it for MMOs sometime back in 2013 (I think) and TMW was one of only a handful of results back then. Sadly that site has long since shut down 
I was browsing through Tux Family wiki and somehow ended up here lol
I'm not exactly sure if it was Jesusalva mentioning TMW in freedroidRPG channel or if it was watching TMW stream from opensourcegaming (https://video.ploud.fr/c/osg/videos?s=1) that brought me to TMW.
I knew about TMW and manasource around 2013-2014, as I was trying to make my own "MMO" at the time. I had a couple emails with Thorbjørn in that time, but I didn't actually play any of the games. Fast forward to late August 2025 and I saw Thorbjørn push the 0.7.0 update to the mana client on github, so I jumped into the discord to say hi and things kind of went from there.
2013.. those were the days of Tremulous for me. Sadly it died off years ago, but TMW lives on. Speaking of TMW, I cannot update my post above, but now that the org rebranding is done, it should be clarified that TMW in that context meant the organisation. OSG was streaming ML.
