Hi Andreas,
Yes, you can use the "My Account" page for managing user profiles, but only if your Website Membership plugin is set to use the "accounts" table. If your front-end logins use a custom user table (WSM_ACCOUNTS_TABLE setting in websiteMembership.php), then you'll need to also use the front-end profile page.
I don't believe there's a built-in way for hiding the CMSB menu, but it would be relatively simple to use the admin_head action in a plugin to output some CSS or JS to hide it under certain conditions, e.g. for non-admin users, or when "?menu=_myaccount".
To hide the entire left navigation, you could add something like this:
<style>
.navbar-content {
display: none;
}
.main-content {
margin-left: 0;
}
</style>
Or to just hide the CMS menu, something like this:
<style>
.main-navigation-menu {
display: none;
}
</style>
Let me know if you have any more questions!
Thanks,
Daniel
