[CB] "Enhance" Users Online in the Info Center

[D-Fox]

Are you tired of an anemic looking Info Center - Users Online? Other BBs, like vB, show users "online" for hours, not a few minutes, when they aren't doing anything. This code adds a calculated subset of selected users that are offline to the Users Online in the Info Center with random dynamics. A selected user that is online will not be shown twice.

- Turn "invisible" mode off for all selected users and ask them to keep it off for maximum effect. It is up to you how you want to handle "admin."

- Edit 4/7/07: Leading comma problem in core code fix - no need to turn off Info Center for Guests.

- Add 15, 30 or more selected users in the code below, examples are shown. Try to add 15 to 20 as a minimum to start. The form in the code for each user is: ['signin name', 'display name', 'group'], -- e.g. ['shelly','Shelly','Pink'],

Leave 'group' as '' if you don't know what it is. This is a one time set up and you can always add or subtract (use //) selected users. Remove any deleted users as soon as possible since clicking on their profile will show nothing, an error.

- If you use name colors, add the following code in the Global Footer AFTER this code. Form is: ('signin name', 'color',''); -- e.g., color('shelly','FF69B4','');
support.proboards.com/index.cgi?board=codedatabase&action=display&n=1&thread=70682

- Tweak the MinAdd and Aggr parameters to your liking. For example, with MinAdd = 3 and Aggr = 0.75 with 9 actual users online, the code will add ( 3 + 0.75*9 +/- 1) = (9,10,11) offline selected users.

- This code is IE and FF compatible.

- Thanks to CrAzY_J for the basic code and Rosss for the basic users online function.

- GLOBAL FOOTER

- Note 5/23/07: The easiest way to check for conflicts is to copy the code exactly as is to the bottom of your Global Footer. The example selected users should start showing up as Users Online in the Info Center. See test site: dfoxtesting.proboards107.com/index.cgi

Edit -- modified -- MinAdd = MinAdd + Math.round( Aggr*userct );
-- to -- MinAdd = Math.round( MinAdd + Aggr*userct );
-- just in case a non-integer is entered for MinAdd -- not critical
