Samerton, this is ItsSteve from Spigot. I have working code for tagging users, it just needs to be modified a bit. Do you want it? I tested it a lot... It works 99.99 (or 100) %.

@fetch404 That'd be really helpful, if you could submit a pull request with the code I'd really appreciate it

@samerton Okay :)

Sorry for not putting the code up, I was having Git problems. Here is the source if you want it (note: you will need to modify this to work with your database setup/model setup)

(note: this is from one of my projects. you can remove the namespace / imports if need be, but you probably shouldn't.) You will have to update any class references.

<?php namespace Fetch404\Core\Services;

use Fetch404\Core\Models\User;

            $matches = $matches[1];
            foreach($matches as $possible_username)
            {

                while((strlen($possible_username) > 0) && !$user)
                {
                    $user = User::where('name', '=', $possible_username)->first();
                    if ($user)

                        break;

                    $new_possible_username = preg_replace("/([^A-Za-z0-9]{1}|[A-Za-z0-9]+)$/", "", $possible_username);

@fetch404 Thanks, I'll work in implementing the class now.
