It seems that I should've explained this before. It is in the rules. We have a ranking system on your profile based on how many posts you've done. The rankings are below.
Baby: 0
Baby II: 5
Child: 15
Adult: 40
Perfect: 75
Ultimate: 125
If you do not have the amount of posts then the number beside the level, you CANNOT evolve/digivolve. Other evolutions may be bought from the shop such as Armor, Jogress, Bioemerging, Burst Mode evolution may be boughten with points at our store. These, may require an signnificant amount of posts to buy as well. However, a higher up staff member such as a Royal Knight may give permission for another to digivolve further without the significant amount of posts BUT do not beg or nag them to do this. It is only if they or I think you deserve it! If they wish to take it up with me just to make sure that is completley fine! In fact, it is highly encouraged.
