Currently this community when using TripleA suffers from some serious problems described and discussed here and - more important - on the triplea-game .org forum.

Everybody feel free to add your concerns to the above mentioned topics. You don’t reach the developer(s) here but over there.
Concerning the Play-By-Forum issue:
For quite some time now the issue is that TripleA has been incompatible with the current forum software (NodeBB). The issue will not be resolved until the forum software and the TripleA software will be ‘harmonized’. Unfortunately I do not know whenever this will happen.
As a workaround you will need to manually send the game history and load up manually created savegames to the forum. You can use ‘Play by Email’ instead of ‘Play by Forum’ to start the game and use the dice server. You don’t need to configure the email settings in the ‘Play by EMail’ form.
