on usa mir you had to join every day anew I think, at first when thousand pple played you needed to log on early in the day to join but later on when interest fell off (or pple leveled past the required level for joining) it was easy to join when you logged on in the evening.
Currently I can't play and so don't know if this noob guild also gives 20% exp bonus like usa mir did? If not, you should definitely consider some bonus.
