The person posting is a Russian speaker doing research at a University on the western border of Estonia and Russia. During soviet times, Narva became a city occupied mostly by Russian residents. Most Russians who moved to Estonia because of military postings or because of the better living conditions in Estonia never learned the Estonian language, even after living there for 20-30 years, so ther person posting is probably not Estonian nor an Estonian speaker.
The post looks like a genuine request for information to me.
Tartu is the leading university in Estonia and is in central Estonia. It seems it probably has a branch in Narva now as well.
(I am fluent in Estonian, which is my mother-tongue although I was born and educated in the USA. I know no Russian, which is an Indo-European language. Estonian and Finnish are in the same language group, the Finno-Ugric languages) which is totally unrelated to any other language groups, as far as I know. (Basque is similar in this regard.)
