Hi. My name is Dedhert.Jr. I am a Wikipedia editor contributing here by glossing articles to be suitably referenced articles;my contribution is mathematics, especially inpolyhedral articles. Over the past months, I have gained many experiences from events or incidents, including how the tensions between users look, how to resolve a problem, and many more. Whenever I contribute here, some users may look at my horrendous action; whenever it does, giving a warning notification is sufficient to remind me how I behaved here (and I will try to fix it). Seemy edits and contributions for more information.

Some of my tools here, or general tools in Wikipedia:
