I have only recently joined the site and it looks very useful.
The question I had is whether it is possible to add your own languages in addition to the standard ones which are available. In my campaign we use a slightly different language set including, in particular, more than one human language. Can this be accommodated in D&D Beyond?
AS of today, no, but that functionality is due in the character sheet revamp coming very soon. Expected by the end of the month.
