...it would help when messages like "what can I buy in the local market" come up when we have no idea where abouts the poster is from.
I'm not sure about that. Even if you know what country they live in, you won't know what's available in the local shops unless you're familiar with whichever city/town/village they live in.
As an aside I tend to assume that anyone using the phrase "in local market" lives either in India or Pakistan. AFAIK, the words "market" and "marketing" have a somewhat different meaning in Indian/Pakistani English than they do in standard English, being closer in meaning to "shop" and "shopping" respectively.
I have to admit that my mental response to that kind of question tends to be along the lines of: "If you don't know what's available in your local electronics store, how the #### am I supposed to know - I live on the opposite side of the planet."
Knowing the country would occasionally help with the other things mentioned though e.g. local electricity.

What I would love to see on the forum is enhanced auto-censorship. At the moment any post containing less than 10 characters is automatically rejected. How about also automatically rejecting any posts containing any of the following:
- All capitals
- No capitals
- More exclamation marks than periods/full stops
- More than three consecutive question marks or exclamation marks
That shouldn't discriminate unfairly against people who's home language isn't English, but it would encourage people to at least attempt to communicate clearly.
