+# Frequently Asked Questions
+
+Some troubleshooting, some general questions about the project! This should help answer any sorta queries you have.
+
+
+## I have a suggestion
+
+Awesome! We love getting new suggestions for features, ways to improve the server and the tooling around it, everything.
+
+There are two ways to make suggestions, either:
+
+- Submit an issue on our [bug tracker](https://github.com/oragono/oragono/issues).
+- Talk to us in the `#oragono` channel on Freenode.

+## Why can't I oper?
+
+If you try to oper unsuccessfully, Oragono will disconnect you from the network. Here's some important things to try if you find yourself unable to oper:
+
+1. Have you generated the config-file password blob with `oragono genpasswd`?
+2. Have you restarted Oragono to make sure the new password has taken effect?
+3. If all else fails, can you get raw protocol output from Oragono for evaluation?
+
+So, first off you'll want to make sure you've stored the password correctly. In the config file, all passwords are bcrypted. Basically, you run `oragono genpasswd`, type your actual password in, and then receive a config file blob back. Put that blob into the config file, and then use the actual password in your IRC client.
+
+After that, try restarting Oragono to see if that improves things. Even if you've already done so or already rehashed, a proper restart can sometimes help things. Make sure your config file is saved before restarting the server.
+
+If both of those have failed, it might be worth getting us to look at the raw lines and see what's up.
+
+If you're familiar with getting this output through your client (e.g. in weechat it's `/server raw`) then you can do so that way, or use [ircdog](https://github.com/goshuirc/ircdog).
+
+Otherwise, in the Oragono config file, you'll want to enable raw line logging by removing `-userinput -useroutput` under the `logging` section. Once you start up your server, connect, fail to oper and get disconnected, you'll see a bunch of input/output lines in Ora's log file. Remove your password from those logs and pass them our way.
