I would like to suggest that the MegaMilestone for Maxwells be changed so that it is displayed when the user earns 2 (happy with 1 actually) of them instead of the current 3.
I have come to the conclusion that this would be sensible by realising that I will probably never reach the dizzy heights of 3 Maxwells, or if I do it will take me quite a few years to do so. This is largely because of the amazing records that some people have set in each of the MegaMilestone categories. Essentially for a middle of the road cruncher like me there are just not enough projects currently running for new crunchers to reach the dizzy heights of a Maxwell in all but the more extreme ends of BOINCing. Check it out - there are maybe 50 active projects at the moment, so the first accessible MegaMilestone to a newcomer is 250K - 50 of them! That's a big ask.
OK a Clanks Maxwell is always going to be accessible to anyone, though only temporarily, and if you know about them in time then Trigggls are too, though Trigggls CAN stop you going for Boks, both of which can impede your ability to get Clanks!

Many people may not even know what a Maxwell is when they see them mysteriously appear - that is cool - it might inspire them.

In a nutshell (yeah - about time too) I feel that if you have earned some Maxwells, then you should see them. 3 is just a tad too difficult to get to for all but the elite top few thousand crunchers, give the littler guy (like me and the many tens of thousands like me) a look in.
Thank you for your time and efforts in providing this excellent site.

PS Can you get a Maxwell for the number of Maxwells you have?
