If a cover letter is not specifically asked for, then I would not worry about providing one. In almost all cases, you are applying for positions electronically now and most of the time, the cover letter is merely an afterthought for a recruiter or hiring manager. Most electronic application processes provide a space to enter a cover letter and if you do decide to use this, keep it short and simple and write something like 'Please accept this as an indication of my great interested in your XYZ position....'. The cover letter was more important prior to the days of electronic applications. Recruiters and hiring managers will not focus as much on it today.
