So for gimplearn.net for each post, I decided to show ppd (posts per day) and post cost.
At bottom of each post before signature you can see the number of posts on the same day as that post, and what that post would cost.
It's just some useless stats purely for fun.
The more posts we have on a certain day (based on post_time) the lower the cost of that post (those posts on that same day).

For even more fun. I have added market value (the least amount the post is worth) based on price listed for gimplearn.com ($2295/year).

Should try to post more there, Tran. Just posted a link to my Deviant for those interested (for seamless textures that is). You have a great site; just spread thin at the moment. Keep up the good work, Tran. Indeed it is expensive to maintain sites and your effort is much appreciated.

Thanks Lyle,
I also just recently added Networth link to member's profile (or when you're viewing posts) it's a link that is after View:Showcase|Slideshow|Networth.
Which calculates a member's networth based on their total posts cost and their estimated market value (just the difference between the two numbers).
It's also for fun and to measure a member's contribution to the forum and I have a note that says please do not start asking me for money for your networth and quit the forum.

Ella on gimplearn.net asked for the cost in EUR (as a joke).
But since it's easy to add links to google to find out what the cost and market values are in different currencies, I did just that for main currencies (CAD,EUR,GBP).
More fun yeah

Since I introduced 4 different methods of calculating a member's networth.
I thought I would show the average net-worth (blue number at bottom after all other methods of calculations [a better representation of a member's worth]).

Am I the only one who's finding all these (could be somewhat fictitious but based on value of the site) net-worth calculations fun to know?

Well, I added net-worth calculations for forums and topics as well. It's interesting to see that some super long topics are worth hundreds of dollars.

I was curious to know what my worth is on gimpchat.com

3034 (my posts on GC) / 213382 (total posts on GC) * $29,250(value of GC)
roughly equals $415.89.

Each post on GC's market value is about
$29,250 / 213382 = $0.137 (or 13.7 cents)

That seems like a lot.

it's according to https://www.worthofweb.com/website-value/gimpchat.com/
