In response to those asking for more MA promotions: yes, it would be the loveliest thing (I loved promoting people - it's one of those fuzzy-feeling moments), but one of the major worries about promotions is whether you're promoting for the right reasons. Numbers and sympathy are the last two reasons anyone should be promoted, and as many of the JAs and SAs have raised, no one wants to have their work devalued, even in the case of receiving a promotion too soon. The question of standards for each rank could be re-evaluated - for instance, how much inconsistency is acceptable (be it between banners and sigs or of a poorly-chosen graphic and the rest of a gallery), but overall, members need to ask what kind of value they place on the JA rank. One has to find the right balance between making JA something valuable and preventing MAs from being discouraged.
Opening up more dialogue with MAs and relentlessly encouraging them would be really productive and much easier to implement. Tutoring has worked well in the past, but as with most of the group activities of the kind members have suggested, it fizzles after the first burst of interest. It would be fantastic if dedicated posters could be there in MA galleries, giving what they can. Anyone, regardless of their own rank and experience, has an opinion on what looks aesthetically pleasing and shouldn't feel unable to express that opinion. All experienced artists offer in critique are suggestions for how to improve (probably because their graphics used to have the same issues and they remember how to fix it).
Cycling the groups is best. Randomly assigning groups, too.
