Are users able to send points to another user? This would be a nice feature. In case they want to trade virtual goods.

No, this is (currently) not possible.

but the old version dont had that problem!! right ?

No, prior to 3.7.14 it has the problem. I tried to fix it in 3.7.14, but this resulted in wrong HTML with not properly closed <a> and damaged username markups.

The API offers to change "musername", but it adds his markup at the end. And there is no other possibility to add awards to this. It would require to catch all places where Awards should be attached.

When installing this, does everyone start from scratch, or will it automatically configure everyone's points based on actions before the install, if I do a manual recount?

If you recount vBExperience will calculate ALL existing data.

vBExperience 3.7.15 is now GOLD. I tried to include most of your wishes and fixed reported bugs.
New to this release are improved promotions and statistics.

How to upgrade?
1. Copy ALL (I mean ALL) files from /upload/ to the server. Espacially take care of the images, copy them to your style misc folder if you use a customized style
2. ReImport product_vbexperience3715.xml, allow overwrite
3. If you modified any of the vBExperience templates, revert them
4. Run Maintenance Tools/Recount

Not all of my members have vbxperience bars and date. The tab shows:
Some members have quite a lot of posts, reputation, etc.
What causes this?

I am getting a lot of the awards myself. How can I exclude myself from awards?

Do you have "Only active users" enabled?
You cannot be excluded explicit from awards.

Is it possible to allow users to buy stuff from the shop for other members?
