Why create one? _ "Re_inventing the wheel", is no fun. If you work for a single organisation it's likely that your templates could last a long, long time with no need to go back to the design board every time you are asked to create a new manual or user guide. When you work for yourself it's a great way to show clients that you have the skills they are looking for without breaking any confidentiality clauses with your existing clients, and with just a little bit of luck they'll adopt your method of working so you can continue to recycle your past efforts too.
You can create professional looking web form templates, just clicking a few times on word. Couldn't believe, right? YES, you can use Microsoft word to create professional form templates for your site. Definitely, it will be a plain one, with no visual interfaces, but this will work like a professional form, trust me!
