Currently, tutors and users follow different registration processes in LanguageLab. The goal is to unify the registration flow for both tutors and users to make it more user-friendly.
The new registration is now available on dev (so also on dev.languagelab.be). I've open a few issues (#173#174#175#176#177 (closed)#178 (closed)) with the (mainly smalls) "bugs" I encounter while testing the registration flow. @LucieBocken If you see other things, don't hesitate to open new issues. I would however advise to wait a bit before trying too hard on dev.languagelab.be as I will try to merge #166 as well for the new study flow, so dev.languagelab.be could become unavailable during the merge.
I also finally chosen to copy the production DB into the dev DB in order to have better control hover the DB upgrade, and I will probably continue to do so for major updates. So you should be able to use your "normal" credentials to login.
