Dear users. Thank you to all who donate to me in this difficult time for my country. Only a small fraction of those who visit this site make donations. If all visitors to this site donated $2 or $0.0004BTC, it would help me survive here. The amount is equal to the cost of a cup of coffee. That’s all I ask. Thank you in advance.

Can anybody help me to translate few my gadgets to other languages (Korean, Thai, Vietnamese, etc.)? If you’re this person, please call me using the contact form.
