Some time ago I accidentally set up the gigameleerumble, while it should have been named meleeTop30rumble. You can remove the gigameleerumble, all bots have around 10-20 pairings.

Honestly, I like the name gigameleerumble better ;-) Maybe we should switch to that instead?

I like gigameleerumble better as well ;) However is there a way to migrate old battles from meleeTo30 rumble to GigaMeleeRumble?

I personally like meleeTo30 since it describes participating bots. GigaMeleeRumble might be confused with ultra-large-sized bots, since we have nano and micro rumbles.

yeah, my first impression on gigarumble was those with code size greater than 1 GigaBytes ;)

However it would be confusing for two similar rumble having quite different name;) and giga also sounds awesome;)
