Thanks for your reply Marc.
1. via spservice i am getting list of all user groups available on the portal ( they are
meaningfull names, so user understands)
2. via "addusertogroups" i am trying to add
an user to the user group's he wants to join
basically the list's item level permission's are based on user groups, and we are allowing the user to control what he wants to see.The problem occurs when the
operaion is being done by someone other than me (who is not the owner of the user groups\sitecollectionadmin)
For obvious reasons the adduser can be done only by owner's or people who are in the group,but
i an looking for a workarround.
what i thought i can do are:
1. on "save" i'll fire a SPD workflow , try and impersonate "ME" and do the "add\remove" there [could not find
a operation called "add\remove user's from groups"]
2. instead of spservice , use a custom wcf ,writecode there and pass my credentials [basically write stuff in c# and deploy, but this
wont work as IT does not allow any kindof deployment]
hope i could give a clear picture .
Thanks again Marc for the help.
