Member Variables
By Paul

In general usage, member template variables begin with {MEMBER. Sometimes however you may be within the scope of some other member yet want to use a variable which is for the person viewing the page. To accomplish this, use {THISMEMBER instead of {MEMBER. The {THIS prefix tells the script that you mean the viewer of the page, not the member whose profile or article we may be dealing with.

{MEMBERSUBMISSIONS} - Number of articles the member has submitted. This is script-neutral, so when used in a different WSN script it shows the appropriate value... useful if you share templates amongst the scripts.
-- Optional parameter: As of 6.0.17, {MEMBERSUBMISSIONS[live]} shows the number of live, non-expired active articles they have. This value isn't cached, so it will slow down the page -- use carefully!
-- Other optional parameters: type name, include unvalidated. {MEMBERSUBMISSIONS[regular]} will count only regular type articles. {MEMBERSUBMISSIONS[regular <,> true]} will count only regular articles, but include articles still pending validation in the count. {MEMBERSUBMISSIONS[false <,> true]} will include all types plus articles still pending validation.
{MEMBERPOSTCOUNT} - Number of comments the member has submitted. This is script-neutral, so when used in a different WSN script it shows the appropriate value... useful if you share templates amongst the scripts.
{MEMBERADMIN} - If viewer can edit this profile, contains the html for the article to do it, otherwise blank.
{MEMBERISADMIN} - Returns 1 (true) if member is an administrator, 0 (false) otherwise.
{MEMBERAVATARURL} - The URL of the member's avatar, for use in an img html tag.
-- Optional parameters: width and height, to make smaller thumbnails of avatars.
{MEMBERALLOWUSEREMAIL} - Returns 1 (true) if member allows emails from other users, 0 (false) otherwise.
{MEMBERALLOWEMAIL} - Returns 1 (true) if member allows emails from administrators, 0 (false) otherwise.
{MEMBERREGDATE} - Date that the member registered.
{MEMBERISGUEST} - Returns 1 (true) if member is an unregistered guest, 0 (false) otherwise.

{MEMBERID} - The id number of the member.
{MEMBERNAME} - The username of the member.
{MEMBERSAFENAME} - If emails are being used as names, this will hide the domain name part of the name to protect from spammers.
