Modification of settings for Esay social

Hi Team,
Please help to understand following issues;

Easysocial: User Name field is non-editable. Is there a way user can edit tat field too as part of profile edit?
Easysocial: Event default approval. On creation of event it should be default approved.
Easysocial: Notification of easy blog rating didnt display in easy social notification.
Easysocial: Photo upload -> Add Location -> Minus sign(-) for minimizing map view level not visible in the MAP window.
Easysocial: Add photo file upload limit set to 8mb but failed to load 6 mb file. is it because i tried with multiple 6 mb file example 5 togather?

Thanks in advance,
Aranb
