BAM is going to be changing profile. The original intention was going to include a full-fledged overhaul including a complete IM system with groups and various other related services such as push notifications, etc. As this is going nowhere, those features will be scrapped. Steam integration, even at the current point, offers a full replacement for RTB Connect. Friends lists, private messaging, group chats and even the main feature people used it for; finding other people who play the game. There is a Blockland group. Join it's group chat.
Rather than try to reinvent the already present and usable wheel and put even more work on an effort that currently isn't getting anywhere, BAM will be reduced to what Blockland actually needs and to what the original idea behind the abbreviation even was ("Blockland Add-On Management"). It is going to include the previously discussed add-ons discovery/hosting service as well as an in-game client for it (and for managing your own add-ons). Smaller features like colorset management will still be included.
