So I develop plugins as a hobby for just over two years now (nothing professional). I've posted one plugin online on a forum for everyone to use. Note that this forum has a rule stating you should write in English. While it's not that big of a deal if you don't, it has basically become a standard that everyone follows. The forum is getting bigger and therefore my plugin is getting more downloads as well. With this also comes more people that require help in using the plugin, are requesting specific features or are reporting any bugs. This is great, I like to hear their suggestions, answer their questions and to help them.
However, sometimes people don't speak English fluently. Most of the time I'm able to make out what they're saying, but sometimes I don't understand anything they're writing. I know how hard it is to learn a second language (English isn't my native language either) so I can completely understand the problems they're having.
How would I reply to these sort of questions? I could ask them to rephrase their question, but I feel like that's very frustrating for the person asking (they are trying to post in a language that's clearly very hard for them and I feel like it's disrespectful to basically tell them their message was unreadable). And even if I ask them to, I doubt the conversation will make any progress, because the next post is probably hard to understand as well.
I could just ignore the message altogether, but I think that's really rude as well, as it might make them feel as if I'm not interested in their message.
I currently have no idea what to do. I only speak two languages (only one of them fluently) and the chance that their native language isn't any of these languages is very high, so asking them to write a post in their native language usually won't result in anything good.
I could learn more languages so that I might understand these messages better in the future, but I think that, because of how long it takes to learn a language, that isn't really going to help that much either.
I always try to write in simple English and keep my sentences short and to the point. I also try to use symbols instead of words whenever I can (e.g. '1' instead of 'one') because they're usually more universal. And while these things make it easier for the other person to read my posts (at least I hope so) it still doesn't make it easier for me to read theirs.
I really want to help these people as well, but at this point it's far better in terms of efficiency and productivity to ignore these messages.
