Description

Madrak's Test Army is a formalized group of users trying to test and find bugs in Roblox. Information in the MTA is communicated up the chain of command. Here are the four ranks: General, Major, Captain, Lieutenant. If you would like to help out, please find a Lieutenant to start contributing bug information to. If you do a good job at finding new bugs, you'll probably get promoted. Membership in the MTA is not guaranteed, and spamming/griefing will not be tolerated. Be sure to follow the rules of your Lieutenant or they will kick you out. To get involved with the group, visit one of our General's groups (http://www.roblox.com/Groups/group.aspx?gid=16143) and start reporting bugs.

Written by the group; not a statement by this register.

Growth

5 measurements spanning 10 days, net +3. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 4,308–4,311 and does not start at zero.
