It is possible to compile a list of observational wishes by combining whatever is known on DGs in general and what could be expected to be found. Such observations would include an extension of the FIR survey to all the late-type DGs in the VC, which would be deeper and more comprehensive than the Tuffs et al (2002) survey. In addition, we would desire a thorough survey to the DGs in the near-IR; this would allow the understanding of the old stellar population, better than what the R or I bands are able to constrain. More HI maps, at least for the HI-rich objects, would allow a better understanding of the internal ISM dynamics; this should be combined with H mapping with an imaging Fabry-Perot interferometer to derive the relation between the neutral and the ionized gas dynamics. More slit spectroscopy should be obtained now that detailed information about the location of HII regions is available from the H images. This would allow the tracing of the metal enrichment within the disk of the galaxy and should be combined with the internal dynamics. In the same line, mapping of the CO and other molecules would also be useful when determining the history of metal enrichment. Finally, all these observational results are only useful if a comparison sample of non-cluster galaxies is available. The definition of such a sample, that would be acceptable by the community, should take a high precedence.
