If you have any questions about using this software, first of all see if the answer is already available in the Help / FAQ section. If you can't find the answer there, try asking on the official World of Tanks forum: TIM topic.
If you wish to report a minor issue, the forum post above is the best place for that.
If the program won't run at all in a new release of World of Tanks, it's best to get in touch with me directly: ws.tim at roman.st. Alternative options: private message on the forum, BitBucket, or a Disqus comment at the bottom of this page.
