Since TMW moved to its own private git instance you now need admin approval for a git account. This is a simple process, but to make it simpler and more accessible I am making this thread. You can request approval here for new accounts.
Please be patient and remember that you don't need a git account to contribute, as your work can always be shared in this forum and pushed to git by someone else. You can view source code and assets for TMW Legacy at https://git.themanaworld.org/legacy (no login needed).
You can find every other project (as well as websites) in https://git.themanaworld.org/explore/groups (again: no login needed)
