I just noticed that I can't edit posts anymore ? the edit button is disabled with the info-tip :

account is not allowed to suggest edits

I googled some and apparently this is caused by having edits being rejected.

Maybe i did not paid attention but how we know that an edit we made is rejected ?

How many rejected edits ban a user from suggesting edits and for how long ?

For my situation when can I be able to suggest edits again ?

Thanks in adavance.
