Thanks for making a thread about it. I was about to start one since I wouldn't have realized we are at a TB if not for a guild officer reminding us, but then I found this one.
I can't understand why CG doesn't get rid of the Galactic Challenge icon, since GCs are in the Events tab, which we are used to check every day anyway since a new event starts every day (Endor omega battles tomorrow, followed by Ground War on Wednesday, General's Command on Thursday and so on).
Or use the space at the left side, as someone said. There's no excuse for 'hiding' important events like this ones. Guild events, where no participation often means getting removed from the guild.
