First off, welcome to the SARP!
I am a Nepleslian GM, as you are making a Nepleslian character in the SMoDIN, your character will be involved in one of the plots or plotships run by us. Our powers do not extend to approving Nepleslian characters in this forum though, but we have to look after our own, eh?
The SARP Wiki, while comprehensive, is sometimes difficult to navigate with outdated or incomplete pages. For the former, the NSS Melissa Keni is no longer running.
This is the page for active plots. There are only two options available to a SMoDIN character though, the more action orientated NSS Acadia, or the social-based Cirrus Station.
Standard issue items for the SMoDIN can be found here. Nothing fancy, just copy and paste.
As for skills,
This page contains the compulsary and boilerplate skills for each occupation of the force. As a 'Field Technician' you'll probably be a Marine with the 'Repair and Maintenance' skill. Copy the skill discriptions from this list wholesale or modify them to suit your character. Basic training counts as a formal education so you do start off with 7 skills, this leaves you with 2 spare skillslots for your character's interests, hobbies or strengths.
Your character aside, each player has to create his own player page on the wiki. Unfortunately for you though, there is already a David on the site and the link in your character's bio links to him. Perhaps you could throw in your last name to differentiate the pages or something?
Well, thats all I could do to help at this point. Make the necessary changes and a character reviewer will be around shortly.
If you need questions answered you can ask them here if it is related to your bio, posting it on the Q and A board or grabbing any one of the older dudes for a one on one. I'm on IRC half the time, but my inbox is always open.
See you around!
