I received some messages related to the ad, so I suppose I'd better specify a few more details.
There are no special conditions, but since I'm doing it for free, I will choose whom I'm going to teach.

Age: any, but I would prefer to communicate with people of my age (28-40)
Gender: any
Language spoken: native English speakers (preferably British English)
Interests: I do not expect to meet orchid breeders or professional musicians here, but it would be nice to meet people who share similar interests.
For more details please visit my profile.

Individual classes will be held via Skype.
The offer is time-limited due to my own personal reasons. It will probably expire sometime around mid-July - early August. It all depends on how soon I'll find the language exchange partners I'm looking for.

Why free? 1. I want to try and see how this works.
2. Interesting chat-partners are a rare species online, so this is my way of solving the problem.

If there are any further questions, feel free to ask them in the thread or write me a message.
