Just a Question...

Is it possible to edit or delete their posts on italiki? Thanks in advance for any explanation!

Thinking better over it,

once it used to be possible to edit or correct an answer, but no delite it;

the comments never had such possibility.

Now an answer may be corrected only writing a new answer or a comment to it.

This coul seem as a severe constrint, but actually it is respectful towards other people

who wrote comments to the answer, and sometimes it also happend tha someone corrected

a weak answer after erading a better one from somebody else.

It is not so fancy, but - due to the limitations of human nature - I think this way it is more fair.

By the way, Italki is not in 'beta' version, only some of its 'new' features are, like the points,

at least this is what the situation seems to me.

I assumed you meant delete *one's own* posts, or edit them - not someone else's of course! And I do think that would be a very good idea - to give the 'author' of any piece of writing more control over it!
