Can anyone tell me when you install the default memberlist1 is an icon supposed to show in the left colum when you are in the admin section?.

It all looks installed right but i can't seem to make anything happen (no icon shows in left colum but it is in blocks)

and i have a feeling this is a module i need.

Could anyone help and maybe describe what is supposed to happen when this is installed and how it works

thanks in advance
