It's been about two years since I first tried to mingle with some people online in the community which English speaking people are dominant. At that time I felt my English fluency is way too weak to join the actively moving forums and discuss things with the members. It was just impossible to follow even the main thread, and I came to a conclusion that I've got to find some other place where I won't be agonized with the lack of fluency of my English.
Luckily, I ran into another community soon where many people from all over the world flock together and talking enthusiastically in English, which, in many cases, is not their mother tongue. The English used there varies a lot and really colorful with the scent of diverse cultures. Should you look at some of the writings with critical mind, then you soon come to realize their writings are not grammatically correct. But it's just a minor thing as long as you can let others know how you feel or what you think about the topic.
I've been in this community for about two years now and I have several friends who kindly give me comments from time to time. It's been really great opportunities for me to practice reading and writing natural English.
Then I started to think if it's the high time to push myself into the community mainly for native English speakers. As you might know by now, I'm such kind of a person who won't hesitate to tackle with a new thing whenever I have a chance and try to find a way to enjoy the challenge as much as I can.
And, today was the day! My challenge turned out to be a successful one thanks to this kind person responded to my introduction message. Here is the exchanges I've done with he/she in the community I joined today. Of course I was nervous at first if my message should sound right there and be welcomed by the members, but I can tell now, if you're careful enough to use polite language, you'll likely have warm messages from the people who share the same interests with you.
me: Hi, everyone. I'm ・・・・・chan from Tokyo, Japan. I'm a native speaker of Japanese. I heard （name of the community) are mainly for people in US, but I hope I can enjoy new things with all of you. Thank you!
member: Hi, ・・・・・chan! Welcome to the group:) Tokyo, haven't been there.
me: Thanks for the welcome message! I'm overwhelmed right now with so many interesting things to check. nice day! ARIGATOU!
member: Don't worry you'll manage it soon enough. I've only been here 7 months myself. It seems overwhelming at first but before you know it you figure out where you fit:)
See? It's not that difficult. All you need is the spirit of challenge and a bit of boldness, I think.
Before you worry too much, find a community good for you and have a try, then naturally your way to go will be stretched father ahead!
