Hi, thanks for opening an issue!

The !joingroup command does not support specifying an amount (as of now).
You can see this in the commands documentation.

It would probably be a good idea to use a standardized format for all commands to reduce confusion.
I think I'll consider changing all relevant commands to use the same !cmd amount destination format in v2.16.0.

Changing tag to enhancement. I'll leave the issue open and update if I have news to share.

this problems i find also in command "addfriend":

Yep, both commands use all accounts and do not take an amount argument.
It is documented in the Commands documentation.

oh, can i make take amount argument for this commands please?

The commands !joingroup & !addfriend now take a amount parameter before the ID parameter, just like all other request commands.
You can also provide the keyword "max" or "all" as the amount parameter to use all available accounts, just like the default behavior before.
If the bot replies with "Joining ... with 0 bot accounts..." then obviously no accounts were eligible to join the group (= are already member of the group).

I'll leave this issue open until Version 2.16.0 is out on the master branch which implements these new features.
