Hi,

following up on [1] we'll soonish [2] purge the following tables from the EventLogging databases:

SignupExpAccountCreationComplete_8539421 SignupExpAccountCreationImpression_8539445 SignupExpCTAButtonClick_8102619 SignupExpCTAButtonClick_8965028 SignupExpCTAImpression_8101716 SignupExpCTAImpression_8965023 SignupExpPageLinkClick_8101692 SignupExpPageLinkClick_8965014 TrackedPageContentSaveComplete_7872558 TrackedPageContentSaveComplete_8535426

If you rely on any of them, please let us know by 2014-08-11.

Sorry for the short notice, Christian

P.S.: The tables will likely pop up again. So do not be alarmed, if you see them appearing again. This is expected. At this point we only care about removing old data from them.

[2] Sorry for being vague here. There are still a few moving parts, but it seems we're purging the data rather sooner than later.
